Scheme  introduction

The electroplating wastewater is complicated and difficult to control in compositions. Besides cyanide, acid and alkali, the wastewater also contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver, etc. the wastewater is highly toxic and may cause cancer, teratogenesis and mutagenesis, which is great harm to human body.


Through Longantai catalytic oxidation technology (pretreatment process), the removal rate of various heavy metal ions such as COD, chromium, cadmium, nickel, copper, zinc etc in wastewater can be reached to 98%, the biodegradability of the wastewater is also improved, and the concentrations of organic pollutants are dereased. The process  plays an extremely important role in ring-opening and chain-breaking of organic matters, so that the biochemical process effect can be long-term stable.
